One of the more complex products to deploy and configure has just been made easier with the release of the xExchange PowerShell DSC Resource Module.
Mike Hendrickson, the creator of these resources, has begun documenting how to use PowerShell DSC to deploy & configure Exchange in the article Introducing the xExchange Module for Powershell Desired State Configuration.
The xExchange module is available via the DSC Resource Kit download page, and by using Install-Module (if you have WMF 5 installed). This set of resources is in direct response to requests from customers like yourselves. If you are working to deploy and maintain Exchange 2013, these resources can be used to solve real deployment issues, and demonstrate how to solve others, by leveraging PowerShell Desired State Configuration.
